METALLIC SCREEN FRAME.

Application filed September 1.6, 1927.

rThis invention relates to improvements in metallic screen frames, and has for its principal object the ion of a metallic frame of this character wl'nch will be strong, rigid and durable, capa ile of maintaining its form and shape for extended periods of time and of such construction as to overcome weaving` or flexing thereof during the handling or operation of the frame.

-W ith these and other objects in view, as vill appear the description proceeds, the invention consists in the novel features of construction, con'ibiiiations of elements and arrangement of parts hereinafter to be more specifically described and pointed out in the appended claims.

ln the accompanying drawing:

Figure l is a side elevation of a screen frame constructed in accordance with the present invention,

Figure 2 is a detail View disclosing fragmentarily in vertical cross section and in perspective the construction of my improved frame,

Figure 3 is an enlarged vertical sectional view disclosing more particularly the corner construction of the frame, and

Figure 4; is a perspective view of one of the corner members of the frame.

Referring more particularly to the drawing the numeral l designates my improved screen frame in its entirety. The 'frame in this instance comprises vertically extending side rails 2 2 and top and bottoin rails 3 and 4 respectively. All of these rails are of identical construction, and a description of one will sui'hce forI all. The meeting edges of the rails are mitered as at 5, and it is the purpose of the present invention to provide improved means for connecting and strengthening or reinforcing these corner portions of the -fran e so as'to produce the desired degree of durability and rigidity.

Each rail is formed from sheet metal and is suitably rolled, bent or otherwise processed to produce a hollow metallic body portion including spaced side walls tie-6, and a transverse bottoni or outer wall 7. The outer wall 6 is provided with a longitudinally extending groove 8, formed by bending the inner of the walls 6 to produce an inner ledge 9 which terminates in an inwardly folded portion 10. The outer of the walls 6 is also bent to provide an inwardly extending ledge 11, which terminates in an up- Serial No. 219,871.

wardly extending wall l2 arranged in engagemr-fnt with the inner of the walls 6. rlhe upper edge of the wall 12 terminates in a transversely extending wall 13, disposed in engagement with the ledge 9 and locked in such position by the inwardly folded wall l0 of the ledge 9. This produces a construction of extremely rigid form for each of said rails and also provides a convenient means for securing the screen body le to said ia. nos shown more particularly in Figure 2 the marginal edges of the body la are bent inwardly to lie within the groove 8, engagin at two of the walls of grooves, and said marginal edges are secured by the pro- Vision of a removable clamping strip l5, which is inserted through t-he open side of the groove 8, and frictionally engages the walls of said groove on the marginal edges ef the screen body to retain the latter firmly in connection with the screen frame. The provision of the strip construction 15, however, facilitates the removal or renewal of the screen body whenever desired. fis indicated in Figure 2 the adjoining walls constituting the groove 8 are spotwelded as at 1G in order to retain the walls in their respective positions and to rigidly unite the same.

Another important feature of the invention is the provision of improved means for Securely fastening the adjoining corner portions of the rails 2, 3 and Il. It is at the corners especially of a frame of this character that weakness is apt to exist and a flimsy, weak and faulty construction produced. In fact, most of the screen frames of metallic construction now in general use contain these faults, and for these reasons architects and builders have heretofore largely preferred the wooden type of frame rather than the metal construction.

l have successfully overcome these objections by providing the corner portions of the frame with internally situated corner members 17, one of which being located in each corner of the frame. These corner members are each formed to include an angularly shaped bar 18 of solid metallic construction, to which are welded angular side plates 19. These plates are cut to conform with the corner construction of the frame, being situated in the hollow spaces provided between the walls 6-6, and are suitably welded to said walls as indicated at 20. These corner members, due to the construction oit the side plates 19., completely occupy the channels 2l formed in the rails between the Walls G-G and are maintained in engagement therewith by the heavy spacing' bars 18. The parts are then Welded together so that a strong homogeneous construction is provided Which completely eliminates flexibility in the frame, overcomes warping` or bending thereof when stored, or in use and provides particularly a metal frame especially adapted for screen construction characterized by strength, rigidity and durability. The construction While'etlicient is extremely ization and facility in manufacture.

What is claimed is:

l. ln a metallic screen frame, a pair of hollow metallic angularly disposed rail sections, a corner member for uniting,T the adjoining portions of said rail sections, comprising a pair of spaced thin metallic plates having angularly disposed leg` portions prising a pair of spaced thin metallic plates having angularly disposed leg portions mounted Within said rail sections to engage closely with the inner Walls thereof, and an angularly disposed spacing' bar having a Width only hall of that oli said plates arranged between the latter, said bar beiner Welded to said plates and positioned along the outer edges thereof and along the outer corner portion of said rails.

ln testimony whereof l a'liix my signature.
